Strange. On my setup, the Nvidia setting has no effect, unlimited in P3D gives about 60 fps when set to half refresh rate in Nvidia.

If I use RTSS and just let it sit there in the hidden icons section, without opening it further, I get around 30fps.

I do not use half refresh rate in NCP..   I use fps=29

Interesting. I used RTSS for months successfully.

Recently I stopped using that and moved to the setting in the later nVidia drivers, and that worked perfect too.

Then the last few flights this week I started to notice bad blurries in flight. I checked the frame rate, and the nVidia setting of 30fps was being ignored. The sim was producing 60fps and struggling.

I checked that the setting was still there in the nVidia control panel and it is, but even after resetting it and re-entering it, it failed to limit the fps to 30.

So right now I'm back on RTSS, which is working fine.

Anyone else had this nVidia limiter fail to work? I'd be interested to know if there is a fix for this.

Okay, recent testing has revealed that there are more rabbit holes in the P3D wonderland than I think we know.

Based upon my respect for Bert Pieke I tried the NCP frame limiter, set to 29. This was effectively the same as my RivaTuner (29.986) setting. Well, to my utter amazement the CPU load (on my rig, at least) decreased significantly, especially for CPU 0. I used to have CPU 0 pegged just sitting on the tarmac, but now it is 50-percent or less, depending upon aircraft. No discernible change in frame rates, but CPU load is very different. Temps seem to be lower as well. One of my favorite aircraft is the Carenado Baron with Ron Attwood's N8UR paint and HawkDSL turbo mods. In addition to being good looking and fast it is very frame-friendly. CPU 0 was consistently less than 50-percent, while the other processor cores running the terrain engines were close or at maximum. I also tried the Alabeo DA-42, which on my rig was a frame hog. While CPU 0 load increased to 80-percent, it was not maxxed-out and this showed in the consistent frame rate and smoothness.

And all this without the "amazing stutter fix"!   🙂
